Bug Description

GNOME 3.22 has two sessions with the same name:
/usr/share/wayland-sessions/gnome.desktop
/usr/share/xsessions/gnome.desktop

LightDM unable to handle this case: both sessions are listed as "GNOME", but the second entry cannot be selected, and only the Xorg session can be started.

Instead of that, LightDM should behave one of the followings:

A) Hide xsession if the corresponding wayland session is available, and use xsession as fallback. This is how GDM handles this case.

B) List wayland-sessions with " (Wayland)" suffix, and make it possible to select them if an xsession has the same name. This is how SDDM handles this case.

Changed in lightdm:
status: New → Triaged
importance: Undecided → Medium
